4mm vs 5mm vs 6mm: SPC Floor Thickness Variations Explained for B2B Projects

SPC floor thickness variation is the first decision most B2B buyers face when specifying floors for offices, hotels, or retail chains. Choosing between 4 mm, 5 mm, and 6 mm options can feel confusing, but each thickness serves a clear purpose. Here’s a simple guide to the three most requested sizes and how to match them to your project needs.

1. 4 mm – Slim, Light, and Budget-Friendly  
Think of 4 mm as the "economy class" of SPC. It’s slim enough to fit over existing floors without raising door thresholds, light enough to reduce shipping costs, and still tough enough for everyday office or hotel corridors. If your space has low foot traffic and you need a quick, cost-effective refresh, 4 mm does the job without breaking the bank.

2. 5 mm – The All-Rounder  
If you want a "one-size-fits-all" solution, 5 mm is the sweet spot. It balances price and performance, giving extra stability under heavy furniture and a quieter feel underfoot. Most shopping malls, classrooms, and restaurants choose 5 mm because it handles busy days without extra weight or cost.

3. 6 mm – Heavy-Duty Comfort  
Picture 6 mm as the "premium class." It adds extra stability for high-traffic airports, hospital lobbies, or luxury hotels where comfort and silence matter. The thicker core reduces sound transmission and feels more solid underfoot, while still fitting standard skirting boards.

4. How to Choose in One Sentence  
- Low traffic, tight budget → 4 mm  
- Mixed traffic, balanced budget → 5 mm  
- High traffic, premium feel → 6 mm  

5. Installation Tip  
All three thicknesses use the same click-lock system, so installers don’t need special tools or extra time—just pick the size that matches your traffic level and budget, and the job runs smoothly.
